Solution
S.P. of 12 glasses
= Rs.600
S.P. of 1 glass
= Rs.`(600)/(12)`
= Rs.50
Profit = 25%
`"S.P."/"C.P" = 1 + "Profit"/(100)`
⇒ `(600)/"C.P." = 1 + (25)/(100)`
⇒ `(600)/"C.P." = (125)/(100)`
⇒ C.P. = `(600 xx 100)/(125)`
= Rs.480
C.P. of 12 glasses
= Rs.480
C.P. of 1 glass
= Rs. `(480)/(12)`
= Rs.40
C.P. of 15 such glasses
= Rs.40 x 15
= Rs.600
S.P. of 15 glasses
= Rs.540
∵ C.P. > S.P.
There is a loss of C.P. - S.P.
= Rs.(600 - 540)
= Rs.60
Loss %
= `"Loss"/"C.P." xx 100`
= `(60)/(600) xx 100`
= 10%.
